Structural Insulated Panels (SIPs) are prefabricated building materials used in residential construction in Alaska. This project prepared resources for homeowners who want to learn about SIPs, where they are used in cold climates, and considerations for Alaska.

Reflective insulation can be effective in reducing solar heat gain in hot, sunny climates but is less effective in cold climates. This project evaluated the effectiveness of reflective insulations in cold climate construction.
